Hi all, 

We just recently started using a 3494 ATL with 3592 drives in our data 
center.  We are also creating our DR tapes using the tape library and ejecting 
the tapes to send to off-site storage.

At our DR site, we do not have a 3494 ATL tape library but we have stand-
alone 3592 drives.  

I'm having trouble deciding how to best set up our DR recovery process.    

Can I maintain the same addresses, for example 600-603 and just change the 
LIBRARY  YES to LIBRARY NO and MTL NO to MTL YES in the device definitions 
using HCD?

I have a feeling I'm going to run into trouble with SMS by doing this.  Do I 
have to create a new MTL definition, storage classes, storage groups, etc.

Initially, we just want to restore the system at the DR site using the 3592 
tape drives.  Longer term, as we utilize the 3494 more and more, we will want 
to be able to run jobs that think they have a tape library available.

Ideally and conceptually, what I would like to do, is operate in ATL mode at 
our data center and in MTL mode at the DR site, with the least amount of 
reconfiguration as possible.

I have no way of testing this before going to the DR site.  All of our 3592 
drives are in the 3494, no standalone drives.  I thought I could define one of 
the 3592 as part of an MTL, but it wouldn't let me bring it on-line because the 
system knows that it is inside the ATL

Any ideas?

Thanks.
